Nowadays, the demand for needle-punched nonwoven fabrics has been increasing, especially in the areas of high-performance composites as reinforcement due to their potential of imparting high Formula: see text-directional strength, easy resin absorption, light weight, and low cost. In this study, needle-punched nonwoven viscose fabric-reinforced epoxy composites are prepared by varying the area density of fabric mat (100Formula: see textgsm, 200Formula: see textgsm, 300Formula: see textgsm, and 400Formula: see textgsm) at constant fabric loading of 30Formula: see textwt.%. The effects of area density on mechanical and slurry abrasion behavior of composites are studied under controlled laboratory conditions. It is observed that the mechanical properties and abrasive wear resistance under steady-state condition has been improved with the increase in area density of fabric mat. Furthermore, experimental design through Taguchi’s LFormula: see text orthogonal array is applied to find out the optimal parametric combination for minimum wear rate. It is also observed through the analysis that silica sand size and sliding velocity are the most influential factors for wear rate.
